In that type of extension tableswherein an extension leaf may be storedbeneath the main top sections, it is common to make the extension leafin two section's'hinged together 6 andhaving a combined length equal tothe width of the table top. 2 In such a construe-f tion it has beenfound diflicult to maintain the adjacent ends ofthe two hinged sectionsin the same plane when the sections are-ex tended and subjected toaload.

, The object of my inventionls to produce a sheet metal hinge of cheapbut effective I form and of such character as to insure proper alinementof the adjacent edgesof the hing ed leaf sections when said sections areextended. The accompanying drawings illustrate my invention. Fig. 1 isan end elevation hinge in leaf-folding position, with portions of theleaves shown in section; I

Fig. 2, a similar view in open position;

Fig. 3, a side elevation of the opened hinge with a leaf section intransverse section;- Fig. 1 a framentary under plan of one side 5 of thehinge and adjacent leaf-sections;

- Fig. 5 a fragmentary top plan, in partial section of, one end of thehinge; and

'Fig. 6 a section'on line'66 of Fig. 5.

Inthe drawings 10, 10 indicate identical strips of metal ofdesiredzlength with its ends turned up to form ears 11 and 12 of equallength, Ear .11 is perforated at. two points 13,13 and ear 12 issimilarly perforated at "15, 15 but the metal immediately j I rangedsheet; metal stripsyof equal length,

around these perforations is struck up to form bosses16, 16 of a heightequal to the. thickness of the connecting levers,t0 be described. At oneside edge car 11 is provided with a ,notch, 17 and the correspondingside 9 edge; of car 12 is provided with-a tongue 18 so formed and placedas to wedge tightly V V I tions thereof-and pivotally connected withcompanion levers, said levers having thick- 7 i into the notch 17 -ofacompanion strip. s

7 Two strips 10, 1O reversed with relation to each other sothat car 11of one lies.,ad-'

ijacent an ear 12 of the other, are connected at each end by twopairs'of L 'shaped levers 20, 21 and 20, 21. The toes of one lever 20and one lever 21 are pivotallyriveted to the outer face of each car 11with their shanks inclined toward the companion hinge strips two pairsof levers 20, 21' are pivotall'y: conofmy improved thehinge. j

of the strip. k I

direction and the ends :of the shanks of the and similarly the toes ofanother lever 20'and i another lever'211arepivotally riveted to the fadjacent ear 12,of the companionfhinge member with their shanks inclinedin theopposite nected :and the, shanks of the-two .le'vers '21 flarepivotallyconnected on anaxis' which will be ina-plane midway betweenadjacent edges 6f the twomembers 10, 10 when they are in the relationshown in Fig.6. i

By providing the bosseslo'theparts will "assemble with 'adjacent earsll'and 12 in the same'plane so that a tongue 18 and a notch Y 17 willproperly c'oact, Screwho-les 25, in

the main strips 10 mynso be formed sym-- E metrically with relation tothe; cars 13 and 1 1 and yet be in alinement with the similarperforationsof the companion platewhen the parts' are assembled, sothatthere will be no 'difliculty. in- 'pre-forming screw holes inthe leafsections: preparatory to mounting When thefhinge partslhave beenproperly assembled as shown, andsecured to "the leaf sections 26, 26, anunfolding of the leaf sections projects the two tongues 18 firmly intothe adjacent notches 17 and, as the fastening screws27 are placedclosetothe planes of the ears, the adjacent edges of the leaves are broughtinto and held in aproper relation to each-other. V j a o I claim as myinvention: r

' 1. A hinge comprising two reverselyj ar the ends of whichare upturnedand perforated, the metal around the perforations of only one upturnedportionof each strip-be ing extended laterally of the portion, two pairsof levers pivotally associated with the adjacent upturned portion at theperforainc 2. A hinge comprising two reversely arranged similar sheetmetal strips of equal length, the ends of which are upturned andperforated, the material around the perforations of only one upturnedportion of each strip extending laterally ofvthe portion, and twopairs'of levers p'ivotsilly associated with the adjacent upturned portions atthe perforations thereof and pivotally connected with companion Elevers,said i'levers having thickness substantiallyrequali'to. saidilaterahextensions, the intermediate portions of each of said stripsbeing provided with two perforations for the reception offasteninghmeans, said perforations being symmetrically arranged relativeto -.the intermediate portions of the strips andithe adjacent verticaledges ofiadjacent upturned portions being formed one with a notch andthe'other with amating tongue which interdigitate laterally of the hingeaxis when-the parts are THOVBCltO open position.

3.1.A,hinge comprising two :main "body strips of equal length with.upturnedears at each end, two pairs of pivotally associated 'levershingedly connecting said strips with the adjacentears there-ofinithe'same plane,

one set of the leversbeingspacedfrom the upturned ends ofone of. saidstripsa distance siibstantially equal to .the thickness of one-lever'inein'ber the adjacent vertical edges-0f adjacent strip endshaving -portions 'which interdigitate transversely and to one side ofthe axis oif'thelhinge,
